Centering continuous variables
WebJan 22, 2024 · Standardizing (centering) variables in regression analysis is recommended when one or more variables in the moderation analysis are continuous variables (e.g., age, height, temperature, distance, etc.) in order to avoid possible multicollinearity issues down the road. In our case, age is a continuous variable. WebYou can't mean-center a categorical variable. Instead, what you need to do is figure out which way you want to talk about the interaction (to determine whether dummy or effect is right for you). If you have 1 continuous & 1 categorical IV (which I assume is binary gender), dummy coding works like this: score one gender as 0 and the other as 1
